Thanks. The ability to take a LAS/LAZ file and convert it directly into a DEM or contour map in DXF format was my primary goal. Then I began getting clients who wanted to model more than just the terrain. Lately I've been contacted by quite a few prospective clients who use drones to scan power line towers and other structures who want to generate models of those structures in addition to the ground.
You may have noticed that I no longer offer the ground classification tools for free. After 421 downloads without even a "thank you" I figured it was time to start charging a fee for it. :-)
